Kelly speaks, Walker doesn’t. Say what?

Javon Walker’s jaw is healthy enough to speak, but he chose not to when it came to Vegas. Tommy Kelly has never spoken to an NFL reporter, but freely chose to for the first time Thursday.

Welcome to Day 1 of Raiders training camp at the Napa Valley Marriott. We’ll break it into digestable chunks.

Walker: A month ago, the $55 million receiver was robbed and assaulted in Las Vegas, left unconcious on the street in the wee hours of the morning, then checked into a hospital.

He reported to camp just fine, save a scar and scab on his forehead. He talked for more than 10 minutes, but wants to leave what happened in Vegas in Vegas for now. Not a bad move in light of an ongoing criminal investigation, since he’s apparently the only eyewitness to his attack.

“When I get ready to come out and tell what really happened, I’ll clear it up then,” Walker said. “It ain’t today. Too soon for that.”

Kelly: Undrafted in 2004, Kelly was given a $50.5 million deal in the offseason — then an NFL record for a defensive tackle.

Even Kelly didn’t see that kind of cash flow coming his way.

“Surprised me, but kind of makes you feel like you’re wanted,” said Kelly, who practiced for the first time since tearing his ACL in October. “I’ll be all right. Responsibility only messes you up when you ain’t ready for it.”

JaMarcus Russell: The “rookie” quarterback made his professional training camp debut. One teammate wondered if Russell even knew how to get to Napa. Consider that a good-natured jab after he sat out of camp last year in a contract dispute.

“I try not to regret anything in life but I wish I could have been here with the guys,” Russell said. “I see what it’s going to be like now from Day 1.”

His throws had zip, he made good reads and spent a lot of time communicating with offensive coordinator Greg Knapp between throws. He had a few flutter balls, but certainly less than we have seen at some offseason workouts.

For the record, Russell said he still weighs 269 pounds.

“At the end of season, the most I’ve ever been is 300 pounds,” Russell said. “Just joking. I was 276.”

Nnamdi Asomugha: Who needs offseason practice? Asomugha finally signed his one-year contract at midnight, reported on time, then jumped a quick route to intercept an Andrew Walter pass intended for Walker during practice.

“I heard all the apocryphal stories during the offseason of what was going on so I wanted to put everything to rest and just show up,” Asomugha said.

Apocryphal? Gotta love that Cal education.
